- 返回名为 <i>time</i> 的列（以秒为单位的 UTC  时间或时间戳）
- 返回具有数值数据类型值的列
- （可选的：返回表示序列名称的名为 <i>metric</i> 的列。如果未找到名为 metric 的列，就将值列的列名用作序列名称）

数据表：
- 返回任何一组字段

宏：
- $__time(column) -&gt; column as "time"
- $__timeEpoch -&gt; extract(epoch from column) as "time"
- $__timeFilter(column) -&gt; column BETWEEN '2017-04-21T05:01:17Z' AND '2017-04-21T05:01:17Z'
- $__unixEpochFilter(column) -&gt;  column &gt;= 1492750877 AND column &lt;= 1492750877
- $__timeGroup(column,'5m') -&gt; (extract(epoch from column)/300)::bigint*300 AS time

group by 和 order by 与 $__timeGroup 联用的例子：
SELECT
  $__timeGroup(date_time_col, '1h'),
  sum(value) as value
FROM yourtable
GROUP BY time
ORDER BY time

或使用这些只返回值的宏来构建自己的条件：
- $__timeFrom() -&gt;  '2017-04-21T05:01:17Z'
- $__timeTo() -&gt;  '2017-04-21T05:01:17Z'
- $__unixEpochFrom() -&gt;  1492750877
- $__unixEpochTo() -&gt;  1492750877
